The first imported case of Oropouche fever in the Canary Islands raises alarm bells for travel-related infections across Europe.
At a Glance
- 19 imported cases of Oropouche virus disease reported in the EU in June and July 2024
- Oropouche virus primarily transmitted by infected midges and some mosquito species
- Moderate risk for EU/EEA citizens traveling to epidemic areas in South and Central America
- Very low risk of locally-acquired OROV disease in the EU/EEA due to absence of competent vectors
- Enhanced surveillance and awareness crucial for early detection and prevention
Emergence of Oropouche Fever in Europe
In a concerning development for public health officials, the Canary Islands have confirmed their first imported case of Oropouche fever, traced back to a traveler from Cuba. This case is part of a larger trend, with 19 imported cases reported across the European Union in June and July 2024. Spain leads with 12 cases, followed by Italy with 5 and Germany with 2.
Oropouche fever, caused by the Oropouche virus (OROV), is primarily transmitted by infected midges and certain mosquito species. While the disease is predominantly found in Central and South America, its appearance in Europe highlights the growing challenges posed by global travel and changing climate patterns.

Understanding the Risks
The European Centre for Disease Prevention and Control (ECDC) has assessed the risk for EU/EEA citizens traveling to epidemic areas in South and Central America as moderate. However, the risk is higher for pregnant women due to potential complications.
Despite these imported cases, the ECDC reassures that the risk of locally-acquired OROV disease in the EU/EEA remains very low due to the absence of competent vectors. However, this situation underscores the need for enhanced surveillance and awareness among health professionals and travelers alike.
Prevention and Awareness
To mitigate the risk of infection, travelers to epidemic areas are advised to use personal protective measures such as repellents, long-sleeved clothing, and insecticide-treated bed nets. Health professionals are urged to increase awareness for early detection of travel-associated cases and to perform laboratory testing for OROV when other arboviral infections are ruled out.

The emergence of Oropouche fever in Europe serves as a reminder of the interconnectedness of global health and the importance of robust public health systems. As we face new challenges from emerging infectious diseases, continued vigilance, research, and international cooperation will be crucial in safeguarding public health.
